Question

I put the WebMethod script below in my .aspx page to connect to my database. However, it seems that I need to put “using System.Data” and “using System.SqlClient” somewhere to use ADO.NET. Can I use WebMethod in .aspx page (not.aspx.cs page) to connect to the database, and if so how should I use it?

<script runat="server">

[System.Web.Services.WebMethod]
public static void send()
{
    SqlConnection con = new SqlConnection("Data Source=.\\SQLExpress;Initial Catalog=Hello;Integrated Security=True");
    SqlCommand cmd = new SqlCommand(queryString, con);
    using (con)
    {
        con.Open();
        cmd.ExecuteNonQuery();
    }
}

</script>
